Less than six months after opening to good but not equivocally great reviews, the newest restaurant from master chef Michel Richard is set to undergo its second round of shakeups.

A reliable source tells us that chef Jon Mathieson, who last manned the stove at the late Inox, also in Tysons Corner, will be taking over the kitchen at Michel at the Ritz-Carlton Tysons Corner. Prior to that, Mathieson was the second in command at 2941 in Falls Church. Mathieson replaces Levi Mezick, who opened the restaurant with Richard last fall.

No date has yet been set for Mathieson's arrival, and it's not known how much, if any, change he will bring to the menu. The 63-year-old Richard has, since opening, added more than a dozen new dishes (including the fried chicken and lobster burgers that have made his bistro, Central Michel Richard, so enduringly popular) and dropped prices in an effort to reposition the restaurant. The mission is to make Michel more like Central and less like Citronelle.
